The time has come - indeed, it has passed, largely unnoticed - to discuss how we approach new cultures.
The teleport network is fascinating, but it also has the potential to transform the societies using it. I mean this in a general sense - who in the village, even amongst those who have not and are not likely to venture out onto the plains and beyond, now views our plateau as the whole of the known world? - but more directly in that it can significantly alter the daily lives of the people around it.
Take the "sea dwarves" of Kassiter. We know almost nothing of their culture, save for the fact that roughly once a year they send a trade caravan to the elves of Klippika.
Let us say that we visit them, and they are friendly. "How did you come here?" they shall ask.
Assuming we do not lie to them they will doubtless wish to witness these marvellous devices for themselves. Once seen, some among them will presumably wish to explore and learn, just as we have. Once they begin to use the teleport network, one of them will doubtless realise that they could run much more frequent trading expeditions to Klippika and Riverglade both, at a fraction of the time and cost of their current arrangements. Reduced costs equals higher profits, so the idea will be attractive. How will the elves feel about this? What effects will this have on their community? Will a regular influx of dwarven goods affect their own farmers, or artisans? Will the dwarves buy up so much food that there is none left for the residents?
Let us imagine that some of the dwarves decide to build a permanent trade post at or near Entatratashan. How will the gnomes feel about this? What effects will this have on their community?
Let us imagine that the dwarves, or some faction amongst the dwarves, become possessive over the network. They decide to restrict the gnomes, or our own, access to the teleporters. How long before armed conflict erupts?
None of these scenarios are by any means guaranteed, but also none are outlandish or presuppose malice amongst the people of Kassiter - they follow logically from the natural motivations of people everywhere: to prosper, to trade, to explore and to know - but also to protect, and to control.
Furthermore, there is also the consideration that somewhere out there in the network are places that were touched by the catastrophe - the black cloud - that perhaps signalled the end of the builder civilisation. If this phenomenon - curse, creature, pathogen or device - is still active, or is dormant but may be activated by our investigations, there's no reason it couldn't spread across the network and bring the same doom to the settlements we know about.
And, indeed, ourselves.
This, then, is our dilemma: to hide the existence of the network, or to deny access to it, seems arrogant and selfish on our part.
Yet to open it up to anyone who wants to use it is dangerous and will absolutely have unforeseen consequences as distant cultures find themselves effectively next-door neighbours with a very low fence.
We have already seen one example of such unanticipated complications - we destroyed the guardians at Entatratradesh, and now the local kobolds have explored it and found Builder weaponry which they have deployed against the gnomes.
What do you think we should do? Are we honest and open about the network and its dangers, in the hope that those we meet will be reasonable about it - as we imagine that we are? Or do we seek to hide and control it, to prevent misuse, whilst possibly fomenting resentment against ourselves from those we should be befriending?
